Segmentation fault at address (various)

Postby Sirprised » 03 Apr 2013, 14:24

Hi

I get the above when attempting to open the graphical interface, whether from the boot menu or manually and with either the default or alternative kernel,
IANAE so if there's a relatively simple pointers to check I'd be grateful. I don't presently have an issue with my Centos install, just being cautious!

TIA

Try the nomodeset boot option to check for kernel problems with modesetting .
Running memtest is also a good idea.
Check also the md5sum of sysrcd.dat to detect a bad CD image.

Thanks for the suggestions.
I've tried the nomodeset option, run memtest for a couple of hours and the image checks out OK and also the CD Graphics window loads OK on an another old PC I have.
I suspect it's connected with an issue reported after Centos recently upgraded to 6.4, including Xorg, after which people reported problems with older ATI graphics.
I've downgraded the drivers as suggested on their forum to 6.3 but it hasn't solved the problem.
I actually have a very old copy of the Rescue CD.0.3.7, which does work so for now I'll make do with that.
Cheers.

Tried you to boot in frame buffer or VESA mode?
Used you wizard "mkxconfig" ?

Hi

Funnily enough I've just tried running the Wizard and if I select the xorg-mkx option, it opens the Graphic environment OK.

Do you know how I make this the permanent option ? I tried the make xorg.conf item but there's no file of that name on my HD! ;-{

Cheers

xorg-mkx write a xorg.conf file in /etc/X11

You can use a autorun script to restore the file while booting.
The easy way to keep the .conf file with the autorun is as a here document in the autorun script.
